Sorry I don't know how to post a photo. She's a Rhode Island Red. The spots aren't tiny speckles but not huge either. They bled when I tried to clean the spots thinking maybe it was was just dirt. Her legs are also not pretty. They are bumpy looking. She acts healthy.
Usually black spots on combs are dried blood and indicate that she has been pecked by another chicken, possibly during a pecking order dispute.
Bumpy legs sound like scaly leg mites. You need to slather them in oil or grease, like Vaseline or coconut oil every 2-3 days for a couple of weeks to treat for leg mites.
